Abstract
In einer Luftkühlvorrichtung für die Kühlung von landwirtschaftlichen Schüttgütern, insbesondere von Körnerfrüchten in Silos und dergleichen, sind zur Kühlung des Schüttgutes zwei Gebläse (1, 2), welche aus der Umgebung Luft ansaugen, parallel geschaltet und können je nach Betriebsverhältnissen wechselweise oder zusammen betrieben werden. Hierbei wird das nach bzw. während der Erntezeit in einem Silo oder dergleichen gelagerte Schüttgut ausschließlich mit Hilfe eines vom Kaltluftgebläse (1) angesaugten, in einem Kühler (3), der gleichzeitig der Verdampfer einer Kältemaschine ist, auf die erforderliche Lagertemperatur gekühlten Luftstromes, der durch eine Leitung (5) in den Silo gefördert wird, gekühlt. Sobald die Außentemperatur soweit sinkt, daß die Leistung der Kältemaschine eine erheblich größere Luftmenge zuläßt als die vom Kaltluftgebläse (1) geförderte Luftmenge, wird das zweite Gebläse (2) zugeschaltet. Eine derart ausgebildete Luftkühleinrichtung ermöglicht einen wirtschaftlichen Betrieb während der ganzen Kühlzeit des Lagergutes.In an air cooling device for the cooling of agricultural bulk materials, especially grains in silos and the like, two fans (1, 2), which suck in air from the environment, are connected in parallel to cool the bulk material and can be operated alternately or together depending on the operating conditions . In this case, the bulk material stored in a silo or the like after or during the harvest is sucked in exclusively with the help of an air flow that is cooled to the required storage temperature in a cooler (3), which is also the evaporator of a refrigeration machine is conveyed through a line (5) into the silo, cooled. As soon as the outside temperature drops so far that the output of the refrigeration machine allows a considerably larger amount of air than the amount of air conveyed by the cold air blower (1), the second blower (2) is switched on. An air cooling device designed in this way enables economical operation during the entire cooling time of the stored goods.
Description
dieses in dem DE-GM 69 32 231 beschrieben ist, im Nebenschluß zum Verflüssiger der nicht dargestellten Kältemaschine angeordnet sein und von dem verdichteten Kältemittel durchströmt sein.this is described in DE-GM 69 32 231, be arranged in the shunt to the condenser of the refrigerating machine, not shown, and of the compressed Be flowed through by refrigerant.
Jedoch können diese Nachwärmer sov,jie der Nachwärmer 7 in F i g. 2 auch von einer fremden Heizquelle, wie z. B. elektrischem Strom beheizt sein. Der Sinn und Zweck dieser Nachwinnung ist in dem genannten deutschen Gebrauchsmuster ausführlich erläutertHowever, these reheaters can as well as the reheater 7 in FIG. 2 also from an external heating source, such as B. be heated electric current. The sense and The purpose of this recovery is explained in detail in the aforementioned German utility model
Sie kann darüber hinaus auch zur sogenannten EslüftungstrockAong verwendet werden. Dabei wird der Luftstrom so weit angewärmt, daß er die Güter nicht nur zu kühlen, sondern auch zu trocknen vermag.It can also be used for the so-called EslüftstrockAong. The Air stream warmed so far that it is not only able to cool the goods, but also to dry them.
Der Einfachheit halber sind Schalter, welche je nach Betriebsverhältnissen das Gebläse 1 und/oder das Geblase 2 ein- bzw. abschalten, nicht dargestellt Diese Schalter werden automatisch durch einen Thermostaten angesteuert, der die Temperatur der Außenluft fühltFor the sake of simplicity, switches which switch the fan 1 and / or the fan 2 on or off depending on the operating conditions are not shown Switches are controlled automatically by a thermostat that senses the temperature of the outside air
Die Betriebsweise von Vorrichtungen, wie sie in den Fi g. 1 und 2 dargestellt sind, ist an sich schon vorstehend erläutertThe operation of devices as described in Fi g. 1 and 2 are shown has already been explained above
So wird während der Erntezeit nach Einlagerung des Schüttgutes in einem Silo od. dgl. in einer ersten Phase aus den eingangs geschilderten Gründen (relativ hohe Außentemperatur und Atmung des Lagergutes) ausschließlich das erste Gebläse 1 in Betrieb gesetzt, die angesaugte Luft in dem Kühler 3 auf die gewünschte Temperatur gekühlt und zur Anpassung der Kaltluftfeuchtigkeit an den jeweiligen Bedarfsfall im Nachwärmer 4 in an sich bekannter Weise erwärmtDuring the harvest period after the bulk material has been stored in a silo or the like, in a first phase for the reasons outlined above (relatively high outside temperature and breathing of the stored goods) only the first fan 1 is put into operation, the Air sucked in is cooled in the cooler 3 to the desired temperature and heated in the post-heater 4 in a manner known per se in order to adapt the cold air humidity to the respective case of need
Sobald die Außentemperatur sinkt und die Kühlung des Schüttgutes eine erheblich größere Luftmenge, beispielsweise die 2fache Menge der durch das Kaltluftgebläse 1 angesaugten Luftmenge, zuläßt, wird das zweite Gebläse 2 in Betrieb gesetzt, so daß während dieser Betriebsverhältnisse in den Silo ein aus dem gekühlten und dem ungekühlten Luftstrom bestehender Luftstrom eingeleitet wird. Sobald die Außentemperatur auf die gewünschte Lagertemperatur absinkt, kann die Kältemaschine abgeschaltet werden, und beide Gebläse in Betrieb gehalten werden.As soon as the outside temperature drops and the cooling of the bulk material allows a considerably larger amount of air, for example twice the amount of air drawn in by the cold air blower 1, the second Fan 2 put into operation, so that during these operating conditions in the silo one from the cooled and the air flow existing in the uncooled air flow is introduced. As soon as the outside temperature reaches the If the desired storage temperature drops, the refrigeration machine can be switched off and both fans in Operation.
